2. Hunted the web and finally found a finnish.dict file. I copied the file
as finnish.0 to the directory I specified in my htdig.conf (I also created
that directory :). Copied finnish.aff there too. (If you cannot find these
files, I can send them to you).

3. I made a list of bad words to the file bad_words

I'm not sure if the machine running htdig has to be configured to be using
the fi-locale. I don't think so, but I changed that just to be sure.
